Application filed May 20, 1916. Serial No. 98,735.

T0 all jwtom t may concern Be it known that I, JOHN DOWLING, a citizen of the United States, and a resident of Powell, in the county of Park and Statev of Wyoming, have invented a new and 1mproved Plow, of which the following is a full, clear, and exact description.

My invention relates to a plow having a pair ef plowshares disposed back to back on the plow standard and a beam adapted to be turned through an angle to present either of the said plowshares at the front.

More particularly the invention relates to a plow in which the plowshares are separately mount-ed on the plow standard for vertical sliding movement and means for simultaneously sliding the plowshares in opposite directions to raise either share and depress the other to working position on the standard.

The invention also includes a novel means whereby to secure the plow beam when adjusted in any one of various angular positions to dispose the handle end for the plowman to follow either in the furrow or on the unbroken land; as well as means to adjust the angular position of the plow handles on the beam.

rFhe invention will be particularly explained in the specific description following.

Reference is to be had to the accompanying drawings forming a part of this specification in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a side elevation of a plow embodying my invention; Fig. 2 is a fragmentary side elevation, parts being in vertical section and others broken out; Fig. 3 is a horizontal section on the line 3 3, Fig. 2; Fig. 4l is a fragmentary side view of the standard showing the opposite side from Figs. 1 and 2; Fig. 5 is an end view of the plow, the beam being in vertical section; Fig. 6 is a horizontal section .on the line (5-6, Fig. 2; Fig. 7 is a fragmentary plan view showing the means for yadjustably mounting the plow handles.

In carrying out my invention in accordance with the illustrated example, a standard, designated generally by the numeral 10 is provided, on which is vertically slidable two separate plowshares, designated generally by the numeral 11. A plowbeam 12 is mounted to turn relatively to the standard through an angle of at least, approximately 180C to reverse the position of the beam relatively to the plowshares, and said beam is provided with handles 13.

.lhe standard is provided with vertical guide channels for the plowshares 11. ln the illustrated construction one side of the standard consists of a vertical plate 14 and at the opposite side, secured to said plate, at the side edges, are vertical strips 15 together with an intermediate strip 16 spaced from the said strips 15 and in the same l plane therewith. Beneath each strip 15 is spacing member 17 is placed of less width, while beneath the intermediate strip 16, spacing members 18' are disposed. The strips 15 and 16 extend laterally at the side edges beyond the respective spacing members, 17, 18, to provide vertical under-cut channels or rabbets between the side strips 15 'and the intermediate strip 16.

The plowshares 11 are provided with vertical members, T-shaped in cross section having guided movement in the under-cut channels in the standard. In the example shown, vertical members 19 are overlapped by the strips 15, 16, and these are secured to' face plates 2O riveted or otherwise secured at one edge as at 21 to the plowshares 11 and bent to extend over the adjacent strips 15 of the standard and to overlap the intermediate strip'l. At the opposite face of the standard 10, each plowshare 11 extends as at 22 to overlap the plate 111 of the standard. Thus, the face plate 20 and the extension 22 receive the side edges 0f the standard between them. `Between the face plate 2O and the members 19, liners or spacing members 23 are disposed and constitute with said members 19, T-shaped slides as clearly seen in Fig. 3.

In order to move the respective plow- Ashares 11 vertically in reverse directions, the sliding members 19 are provided with rack teeth 19l`on their opposed edges, and

meshing with said rack teethis a pinion 211- on a transverse shaft 25, which is provided withy a crank handle, 26. Thus, by turning the handle, the pinion 24; will raise one plowshare 11 and lower the other to the working position at the lower end of the standard. Any suitable means may be provided for locking the handle 26 against turning after a given adjustment of the plowshares; l have shown for the purpose a pin 26u projecting laterally7 from the standard, the handle being formed with a l The face plate 2O oteach plowshare is secured to the `shaped slides, consisting of the elements, 19, 23, through the medium of bolts 28. One bolt 28 of each plowshare is utilized tosecure the inner end of the brace 27, the `outer end of which is suitably fastened as at 28 to the mold-board. To effect the pivotal connection of th beanr12 with the standard, the said standard is provided with a turntable 29 at its upper end, secured by brackets 30 or equivalent means, and the under side of the plow beam is provided with a wear plate 31 turning on said turntable. On the upper side of the standard may be secured a plate 32. A pivot pin 33 extends through the turntable 29 a-nd through the plow beam centrally through the plates, 31, 32, and is provided with a nut 34. The beam is thus adapted to be turned through an angle to reverse the Vpositions of the handles 13 relatively to the rplowshares 11 and dispose the clevis end 12u of the beam properly with respect to either share.

To'secure the beam in adjusted position, a vertical pin 35 or its equivalent, is employed, to receive which the beam is provided with vertical pin holes 36, there being corresponding pin holes 3T in the turntable 29. lt will be observed from Figs. 2 and 6 that series oi' holes 36,37 are produced in the plate 31 and turntable 29 and 'out of line radially, the purpose of which is to vary the angle of the beam to dispose the handle end thereof so.

that the plowman may walk in the furrow or on unbroken land.

The numeral 38 indicates rivets or bolts for securing the plates, 31, 32, to the beam. The numeral 39 indicates a bolt or pin extending vertically through the beam 12, adjacent to the periphery of the turntable 29 and plate 31, said pin having at its lower end a washer or collar 40 projecting laterally to engage beneath the said turntable. rlhe pin or bolt 39 is provided with a pivoted cam lever 41 at its upper end to bind the member 40 against the under side of turntable 29.

The numeral 42 indicates rivets for securing the elements, 15 and 17, and 16 and 18, to the plate 14 of the standard.

In addition to providing the pin 35 and the pin holes for eiiiecting the angular adjustment of the beam 12, l provide means to vary the angles or the handles 13 to the beam; for the purpose a plate 43 is Secured to the said beam by bolts, 44, 45. The upwardly extending sides 46 of the plate 43 are flanged as at 47 over the upper sides of the handles, and additional bolts 48 pass through the said handles and the sides 46. The bolt 44 extends through a curved slot 49 in the plate 43 and receives a wing nut Thus, the handles 13 with the plate 43 may be swung to either side with the bolt 45 as a pivot and secured in the adjusted position by the nut 50, whereby to dispose the handles at a. suiiieient angle to the plow beam Y 4for the plowman to follow the furrow or walk on the unbroken land.

I wish to state in conclusion that although the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied without departure from the spirit et' the invention as defined in the appended claims.

Having thus described my invention l claim as new, and desire to secure by Letters Patent:
